[0002] With the development of modern technology, users have higher and higher requirements for electronic devices. In order to meet the user needs and improve the operation convenience of electronic devices, manufacturers often set buttons and display patterns for indicating button functions on the outer surface of the housing of electronic devices. However, the two are often arranged separately, which will result in a large space occupied inside the housing, resulting in a large volume of the electronic device and being unfavorable for the miniaturization development of the electronic device. Summary of the Utility Model

A display pattern is set on the keycap so that the button structure can have a display function, which can reduce the space occupied inside the housing to reduce the volume of the housing, and further make the electronic device have a smaller volume.

[0004] The embodiments of this application provide a button structure installed in a housing. The housing has a button hole. The button structure includes a keycap, a soft rubber part, a circuit board, and a pressing part. The keycap has a display pattern, and at least a part of the keycap is exposed through the button hole; the soft rubber part includes a deformation part and a connecting part. The connecting part surrounds the periphery of the deformation part. The deformation part is connected to the inner surface of the keycap, and the connecting part is used to be connected to the inner wall of the housing; the circuit board is provided with a light-emitting component and a button. The keycap is correspondingly arranged with the button. The light emitted by the light-emitting component is emitted through the display pattern; the pressing part is connected to the circuit board, and the pressing part is used to be connected to the inner wall of the housing and squeeze the connecting part.

[0005] The embodiments of this application also provide a housing, including a housing and a button structure. The housing has a button hole; at least a part of the keycap is exposed through the button hole. The pressing part is connected to the inner wall of the housing and squeezes the connecting part.

[0006] The embodiments of this application also provide an electronic device, including a housing and components. The components are arranged inside the housing and are electrically connected to the circuit board.

[0007] Based on the key structure of the present application, by setting a display pattern on the keycap and using a corresponding light-emitting component, the key structure can have a specific display function for the set display pattern, facilitating users to identify the function of the key structure according to the display pattern, and further facilitating users to operate the electronic device according to the display pattern, improving the convenience of user operation of the electronic device and the operation efficiency of users. Moreover, compared with the separate setting of the components of the key structure and the display function, the integration of the display function components into the key structure makes the key structure design compact, reducing the space occupied by the key structure in the housing, thereby reducing the volume of the housing and further making the electronic device smaller in size.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] To make the objectives, technical solutions, and advantages of this application clearer and more understandable, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain this application and are not used to limit this application.

[0015] Please refer to Figure 1 , an embodiment of this application provides an electronic device 1, including a housing 2 and components (not shown in the figures) disposed within the housing 2.

[0016] The housing 2 can support and protect the components disposed within the housing 2. The material of the housing 2 can be plastic or metal. Specifically, the material of the housing 2 can be plastic, so that the housing 2 is insulated, thereby reducing the risk of electric shock to users. And because the plastic material is lighter in weight, the housing 2 is lighter in weight, so that the overall weight of the electronic device 1 is lighter, facilitating the portability of the electronic device 1. Specifically, the housing 2 can be integrally injection-molded, so that the housing 2 has high structural strength, making the housing 2 not easily damaged, capable of protecting other components within the housing 2, reducing the probability of damage to other components, and thus enabling the electronic device 1 to have a longer service life.

[0017] Exemplarily, the electronic device 1 can be any one of a charging device, an energy storage device, a headset, an electric toothbrush, and a floor cleaning robot. In other embodiments, the electronic device 1 can also be a device in other forms and functions. In the embodiments of this application, the specific form of the electronic device 1 is not limited.

[0018] Please refer to Figures 1-3 , in one embodiment, the housing 2 includes an outer shell 21 and a button structure 3. The outer shell 21 has a button hole 21A.

[0019] The button structure 3 includes a keycap 31, a soft rubber part 32, a circuit board 33, and a pressing part 36.

[0020] The keycap 31 has a display pattern 311A, and at least a part of the keycap 31 is exposed through the button hole 21A for the user to press the keycap 31. Exemplarily, the display pattern 311A includes at least one of a function indication pattern, a Chinese character pattern, and an English pattern. In the embodiments of this application, the display pattern 311A can be a power pattern or a volume pattern. Exemplarily, the keycap 31 can be circular, triangular, quadrilateral, or polygonal. In the embodiments of this application, the shape of the keycap 31 is not limited.

[0021] The soft rubber component 32 includes a deformation part 321 and a connecting part 322. The connecting part 322 surrounds the periphery of the deformation part 321. The deformation part 321 is connected to the inner surface of the keycap 31, and the connecting part 322 is used to connect to the inner wall of the housing 21 so that the keycap 31 is connected to the housing 21. When the user presses the keycap 31, the keycap 31 moves in the keyhole 21A in the direction close to the circuit board 33, causing the deformation part 321 to undergo elastic deformation. When the keycap 31 is released, the deformation part 321 returns to its original shape, pushing the keycap 31 in the direction away from the circuit board 33, facilitating the user to press the keycap 31 next time. Exemplarily, the material of the soft rubber component 32 includes but is not limited to at least one of silicone, rubber, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), soft polyvinyl chloride (PVC), and polyurethane (PU). In other embodiments, the soft rubber component 32 can also be made of other materials.

[0022] The circuit board 33 is provided with a light-emitting component 34 and a key 35. The keycap 31 is correspondingly arranged with the key 35. The light emitted by the light-emitting component 34 is emitted through the display pattern 311A to light up the display pattern 311A, thereby facilitating the user to identify the function of the key 35. Exemplarily, the light-emitting component 34 can be at least one of a lamp bead, a light bar, or a display screen. In the embodiments of the present application, the specific form of the light-emitting component 34 is not limited. Exemplarily, in the embodiments of the present application, the light-emitting component 34 can be LED lamp beads of different colors so that the display pattern 311A can display different colors.

[0023] The pressing component 36 is connected to the inner wall of the housing 21 and presses the connecting part 322, causing the connecting part 322 to deform to fill the gap between the pressing component 36 and the housing 21, thereby reducing the probability of liquid entering the electronic device 1 through the gap between the pressing component 36 and the housing 21, reducing the probability of component damage, enabling the components to have a longer service life, and further enabling the electronic device 1 to have a longer service life. Exemplarily, the pressing component 36 can be screwed or glued to the housing 21 to make the connection between the pressing component 36 and the housing 21 stable. The circuit board 33 is also connected to the side of the pressing component 36 facing the housing 21, so that the pressing component 36 can be used to fix the circuit board 33 to ensure that when the user presses the keycap 31, the keycap 31 can trigger the key 35, and further enable the electronic device 1 to respond to the user operation.

[0024] In the embodiment of the present application, by setting a display pattern 311A on the keycap 31 and using a light-emitting component 34 correspondingly arranged therewith, the key structure 3 can have a specific display function for the set display pattern 311A, facilitating the user to identify the function of the key structure 3 according to the display pattern 311A, and further facilitating the user to operate the electronic device 1 according to the display pattern 311A, improving the convenience of the user operating the electronic device 1 and the operation efficiency of the user. Moreover, compared with the separate setting of the key structure 3 and the components with display functions, the integration of the display function components in the key structure 3 can reduce the space occupied in the housing 21, so as to reduce the volume of the housing 21, and further make the electronic device 1 smaller in volume.

[0025] Furthermore, since the pressing member 36 can squeeze the connecting portion 322, causing the connecting portion 322 to undergo elastic deformation to fill the gap between the pressing member 36 and the housing 21, the probability of liquid entering the electronic device 1 through the gap between the pressing member 36 and the housing 21 is reduced, so as to reduce the probability of damage to the components in the electronic device 1, and further enable the electronic device 1 to have a longer service life.

[0026] It can be understood that the components in the housing 2 can be electrically connected to the circuit board 33, so that the user can press the keycap 31 to cause the key 35 to generate corresponding electrical signals, and the circuit board 33 controls the corresponding components to perform preset operations through the corresponding electrical signals. Exemplarily, when the electronic device 1 is a charging device, the user can control the output port to supply power to an external device by pressing the keycap 31; or can control the output port to stop supplying power to the external device. For example, when the electronic device 1 is an electric toothbrush, the user can also control the motor to work by pressing the keycap 31, so that the motor can drive the brush head to move, thereby cleaning the user's oral cavity; or can control the motor to stop working.

[0027] Please refer to Figures 1-3 , in an embodiment, the keycap 31 includes a body 311 and a light guide member 312. The body 311 has a display pattern 311A and is connected to the deformation portion 321; the light guide member 312 is connected to the body 311, the light guide member 312 extends in the direction close to the key 35 and is correspondingly arranged with the key 35. The user presses the body 311 to cause the body 311 to move in the direction close to the key 35, so that the light guide member 312 moves in the direction close to the key 35 to trigger the key 35. The light guide member 312 is correspondingly arranged with the display pattern 311A, and the light emitted by the light-emitting component 34 is emitted through the light guide member 312 and the display pattern 311A to light up the display pattern 311A, thereby facilitating the user to identify the function of the key 35 and improving the operation accuracy of the user.

[0028] Please refer to Figures 1-3, Specifically, the deformation part 321 may have an avoidance hole 321A and a light guide cavity 321B. The light guide cavity 321B is communicated with the avoidance hole 321A. One end of the light guide member 312 away from the main body 311 passes through the avoidance hole 321A and is disposed in the light guide cavity 321B. The light emitting member 34 is correspondingly arranged with the light guide cavity 321B. The light emitted by the light emitting member 34 can enter the light guide cavity 321B and is emitted through the light guide member 312 and the display pattern 311A to light up the display pattern 311A and provide a display function for the user.

[0029] It can be understood that the display pattern 311A may include at least one of a transparent part and a light transmission port 311B.

[0030] Please refer to Figure 2 and Figure 3 , Specifically, the main body 311 has a light transmission port 311B. The light guide member 312 has a pattern part 3121 and a pressing part 3122. The pattern part 3121 is embedded in the main body 311 and is partially exposed through the light transmission port 311B to form the display pattern 311A. The light emitted by the light emitting member 34 is transmitted to the pattern part 3121 through the pressing part 3122 and is emitted through the light transmission port 311B to light up the display pattern 311A. The pressing part 3122 is correspondingly arranged with the key 35. When the user presses the key cap 31, the main body 311 will move in the direction close to the key 35, so that the pressing part 3122 moves in the direction close to the key 35 to trigger the key 35.

[0031] It can be understood that the pattern part 3121 may be bonded to the inner wall of the light transmission port 311B to improve the connection stability between the pattern part 3121 and the main body 311. Furthermore, when the user presses the key cap 31, it can be ensured that the pressing part 3122 can trigger the key 35 and respond to the user's operation.

[0032] Please refer to Figures 1-3 , in the embodiment of the present application, both the main body 311 and the light guide member 312 may be made of plastic material. The main body 311 and the pattern part 3121 can be integrally formed by a secondary injection molding process to eliminate the gap between the main body 311 and the pattern part 3121, so as to prevent liquid from entering the key structure 3 through the gap between the main body 311 and the pattern part 3121, reduce the probability of damage to the key structure 3, and further enable the key structure 3 to have a long service life, so that the electronic device 1 can have a long service life.

[0033] Moreover, since the main body 311 and the pattern part 3121 are integrally formed by a secondary injection molding process, the gap between the main body 311 and the pattern part 3121 is eliminated, which can reduce the probability of dirt and grime accumulating in the gap between the main body 311 and the pattern part 3121, improve the cleaning convenience of the electronic device 1 for the user, and also provide a reliable guarantee for the physical health of the user.

[0034] Furthermore, since the main body 311 and the pattern portion 3121 are integrally formed by a two-shot injection molding process, compared with the bonding of the main body 311 and the pattern portion 3121, the assembly steps of the main body 311 and the pattern portion 3121 can be reduced, so as to reduce the assembly steps of the key structure 3, thereby improving the assembly efficiency of the key structure 3 and further improving the assembly efficiency of the electronic device 1.

[0035] It can be understood that the main body 311 and the pattern portion 3121 can be integrally formed by a two-color injection molding process, which can also eliminate the gap between the main body 311 and the pattern portion 3121, and can also reduce the assembly steps of the key structure 3, improving the assembly efficiency of the electronic device 1. In the embodiments of the present application, this will not be elaborated too much.

[0036] Please refer to Figures 1-3 , in an embodiment, the inner surface of the main body 311 can be bonded or screwed to the deformation portion 321 to improve the connection stability between the deformation portion 321 and the main body 311, so that after the user presses the key cap 31, the deformation portion 321 can push the main body 311 in a direction away from the key 35, facilitating the user to press the key cap 31 next time.

[0037] Please refer to Figures 1-3 , in the embodiments of the present application, both the main body 311 and the deformation portion 321 can be made of plastic material, and the main body 311 and the deformation portion 321 are integrally formed by a two-shot injection molding process to eliminate the gap between the main body 311 and the deformation portion 321, thereby preventing liquid from entering the key structure 3 through the gap between the main body 311 and the deformation portion 321, reducing the probability of damage to the key structure 3, and further enabling the key structure 3 to have a long service life, so that the electronic device 1 can have a long service life.

[0038] Furthermore, since the main body 311 and the deformation portion 321 are integrally formed by a two-shot injection molding process, compared with the bonding of the main body 311 and the deformation portion 321, the assembly steps of the main body 311 and the deformation portion 321 can be reduced, so as to reduce the assembly steps of the key structure 3, thereby improving the assembly efficiency of the key structure 3 and further improving the assembly efficiency of the electronic device 1.

[0039] It can be understood that the main body 311 and the deformation portion 321 can also be integrally formed by a two-color injection molding process, which can also eliminate the gap between the main body 311 and the deformation portion 321, can also reduce the assembly steps of the key structure 3, and further improve the assembly efficiency of the electronic device 1. In the embodiments of the present application, this will not be elaborated too much.

[0040] Please refer to Figures 1-3, in the embodiment of the present application, the body 311, the pattern part 3121, and the deformation part 321 are formed as a whole, which can reduce the assembly steps of the button structure 3 and also reduce the assembly complexity of the button structure 3, thereby improving the assembly efficiency of the button structure 3 and further improving the assembly efficiency of the electronic device 1.
